ALLOY IIETAL.

Ho Drawing.

To all whom it may concern:

Be it known that I, ABEL S. HATFIELD, a citizen of the United States of America, and residing at Wheeling, county of Ohio, and

State of West Virginia, have invented certain new and useful Improvements in Alloy Metals, of which the following is a specification.

llhis invention relates to a new metal 10 alloy, or an alloy of metals, which possesses certain peculiar characteristics and properties which render it particularly valuable for use throughout practically the entire field of engineering.

The invention comprises cobalt, molybdenum and tin, with which are mixed, during the amalgamation process, small percentages of sodium carbonate and a keratinoid substance, such, for instance, as horn.

Said metals are mixed in approximately the following proportions by weight:

Cobalt, 7 5 per cent; molybdenum, per cent; and tin, 5 per cent.

The sodium carbonate and keratinoid materia'l are added during melting, approximately one-fourth pound of each being used to each one-hundred pounds of the mass. The sodium carbonate acts to amalgamate m-ately, 75%

the metals for producing a homogeneous alloy product, while the horn or other kera tinoid material employed, acts apparently as a deoxidizer and renders the product materially harder and'tougher. The tin itself apparently acts as a solvent for the molybdenum.

What is claimed is;

1. An alloy metal' comprising cobalt, molybdenum and "tin, in which the cobalt predominates and the percentage of molybdenum is more than double that of the tin.

2. An alloy metal comprising cobalt, molybdenum and tin in which the percentage of cobalt is more than three times that of the molybdenum and the percentage of of molybdenum is more than twice that of the tin. w v

3. An alloy metal comprising, approxicobalt, 20% molybdenum, and

5% tin.

In testimony whereof, I- afiix my signature in presence of two subscribing witnesses.

ABEL S. HATFIELD.
